Queensland Premier Annastacia Palaszczuk has slapped down One Nation's claims that teachers are showing children sex tricks in the classroom as "absolutely atrocious" and untrue.

The stunning allegations came from the party's Queensland leader Steve Dickson as he tried to defend his party's domestic violence policy and its promise to abolish the Safe Schools program, if elected.

"One Nation is about protecting the whole family unit," he said.

"And that takes me onto another note — the controversial Safe Schools program in Queensland.

"We are having little kids in grade four at school, young girls being taught by teachers how to masturbate, how to strap on dildos, how to do this sort of stuff — that is the real problem in this country."
